5100 Kanata Avenue Blasting Information

The seismographs for 5100 Kanata/130 Goulbourn Forced (the new site of the Hawthorn Retirement Residence) can be foundhere (click for link).

The most important lines for residences are the PPV and 2C Frequency, seen below in the tables:

PPV (peak particle velocity) is what the seismograph measures and is the unit of reference for ground vibrations. The limit, set by the City of Ottawa, is at 50.00 mm/s.

ZC Frequency refers to the frequency of the PPV. There are special provisions from the City of Ottawa that dictate the standard levels of the blasting. More information about them will be put on the site if there are updates.
